Competition in Arabidopsis thaliana (L.) Heynh., behaviour of Mimosa pudica L. and a new method to characterize roots demonstrated with Helianthus annuus L..

In this dissertation, I address 5 problems in the discipline of plant ecology: two problems in plant competition, two problems in plant behaviour and one problem in the phenotyping of plant roots. First, we directly test Darwin’s competition-relatedness hypothesis with a pairwise...

The worldwide biodiversity crisis has intensified the need to better understand how biodiversity and human disturbance are related. Yet this relationship lacks both consensus in theoretical expectations and consistency in observed empirical patterns. I present one of the largest extent studies...

Rebuilding the boreal: analyzing the replicability of the bacterial community structure and soil functioning of forest floor mineral mix with peat subsoil admixtures
DownloadSpring 2017
Alberta law requires reclamation of lands disturbed by surface mining operations, such as those occurring at the Athabasca Oil Sands Region, however, reclamation rates lag far behind continued disturbance rates. Due to cost, mining companies must make use of the materials on site, of which the...

Roots in reconstructed soils - how land reclamation practices affect the development of tree root systems
DownloadSpring 2018
Tree root systems are incredibly complex organs that fulfill several vital functions, the main ones being anchorage and uptake of water and mineral elements. They perform these functions in a highly complex and challenging soil environment with heterogeneously distributed soil resources, physical...

Transcriptome and Proteome Based Survey to Identify Aluminum-Responsive Genes in Roots of Arabidopsis Thaliana
DownloadSpring 2010
Aluminum (Al)stress is a major limitation to crop productivity on acidic soils. To help understand the cellular mechanisms underlying the toxicity and resistance of plants to Al, this thesis involved a large-scale, transcriptomic and proteomic analysis of roots of Arabidopsis thaliana and reports...

Transfer of live aspen roots as a reclamation technique - Effects of soil depth, root diameter and fine root growth on root suckering ability
DownloadFall 2012
A transfer of live trembling aspen (Populus tremuloides Michx.) roots including the surrounding forest floor was conducted to examine aspen’s ability of vegetative regeneration to establish a boreal forest on a reclamation site. Forest floor was salvaged at two depths (15 cm and 40 cm) from a...
